(9x^2 + 21x + 10)= (3x+5)( 3x+2)+0
n is the initial amount
0.07 is the factor of increase
x is the number of years that the emails increased
answer: C
Answer:
Step-by-step explanation:
The pillow is cylindrical. To determine the amount of fabric needed for the pillow, we would apply the formula for determining the total surface area of a cylinder which is expressed as
Total surface area = 2πr² + 2πrh
Where
r represents the radius of the cylinder.
h represents the height of the cylinder.
π is a constant whose value is 3.14
From the information given,
radius = 5 inches
Height = 18 inches
Therefore,
Area = (2 × 3.14 × 5²) + 2 × 3.14 × 5 × 18
Area = 157 + 565.2 = 722.2
Amount of fabric needed is
722.2 square inches
Answer: 40 days
